Mind-Controlled Appendage Used Successfully by Apes

Scientists at the University of Pittsburgh performed an experiment in which they used a monkey to control a robotic arm using its mind. The monkey in the video is actually feeding himself using the robotic arm.

Jason Chen stated, "If these test work—which they look like they do, the monkeys are feeding themselves successfully—you too can lop off your own arm, stroll into the emergency room, and feel confident that they’ll replace your missing appendage with the robotic equivalent. No wait! We mean in a couple of years!"
